Somewhat interesting, if you're into this sort of thing. According to the Wall Street Journal, the Pew Research Center has released a study that says while many a millennial isn't leaving the nest, males are significantly more likely to be the one's who remain couchside:
Millions of young Americans are living at home, according to a Pew Research Center analysis of U.S. Census Bureau data. The number of “millennials” -- adults aged 18 to 31-- living at home rose to 36% last year. That represented the highest percentage in the last four decades, and a significant increase from 32% just five years earlier. In 2012, 56% of adults aged 18 to 24 lived in their parental home, Pew found, as did 16% of adults aged 25 to 31. However, millennial males (40%) were significantly more likely than millennial females (32%) to live with mom and dad.
The article goes on to express many theories, including that there are more, single unmarried men than there are women (women, on average, get married slightly earlier), that men are given more parental freedom than women while at home, and that because women tend to do better in the education system, the DUMB MEN have a more difficult time getting jobs that pay money.
I lived at home for a few months transitioning from college to this fine job, and had the commute not been 2 hours each way, I probably would've stayed home a lot longer. It's a very simple equation. No rent + a lot of free meals = a lot of money to do cool stuff. If your parents are cool/aren't weird with bringing people home,* don't really get in your way, and live somewhere that's convenient for your job/life, they can end up being pretty phenomenal housemates. Nowhere else could you empty the dishwasher 1 out of every 20 times and be considered a hero.
Plus, you know what they say--we're a pretty aspirational generation.
*A one night stand sitting down to breakfast with your parents could be a truly tremendous experience for all involved.
